In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

  - flare - not performed, pilot in command (cause)
  - weather condition - high density altitude (contributing factor)
  - weather evaluation - not performed, pilot in command (cause)
  - landing gear,nose gear - overload

## Analysis

THE PLT MISJUDGED THE FLARE DURING LANDING AND THE ACFT TOUCHED DOWN IN A NOSE LOW ATTITUDE SHEARING THE NOSE GEAR FROM THE ACFT. THE DENSITY ALTITUDE WAS CALCULATED TO BE 3,500 FT WHEN THE ACCIDENT OCCURRED.

## Other investigations on N7338F (2)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
